WILLIAM v. JUSTICE AND HUGH ALLON STEWART, F BOBSITEB, PENNBYLVANIL BRAKE.

Application led January 19, 1926. Serial No. 82,309.

This invention relates to improvements in brakesl particularly adapted for use in connection with automobile wheels, and has for its object to provide a brake of the conetype which shall be of simple construction and eiiicient in use.

The various features of novelty and in-l vention will appear from the detailed description taken in connection with the accompanying sheet of. drawings forming a.

part of the specification.

Referring to drawings, Fig. 1 is a view partly in section and partly in elevation showing the improved brake.

Fig. 2 is a view showin the operating yokey or lever by means of whlch the brake is operated. p In the drawings, 1 indicates the conventional rear axle housing within which is, contained the drive shaft 2, and on which is mounted the wheel 3. Secured to the wheel is'the conventional type of brake drum having a laterally directed flange 4. Arranged within the drum is an annular friction mem- `to the brakev drum flange 4 in any suitable manner as by means of screws 6. Cooperating with the friction member 5 isa cone member 7, this member being slidably mounts ed on the housing 1 as by means of radial ribs or keys 8. The cone member is adapted to be shifted into contacting relation with friction member 5 by a lever 9 ofY-type, said lever being lpivoted as at 10 to a radially projecting brac arms 12 of the lever overlie the housing on Referring to Fig. 1, it will be noted thatthe annular friction member 5 isliared upber 5, this member being removably secured' of brake, it is merely necessari et 11 on housing 1. The.-

either side thereof and are connected to studs wardly and outwardly from the wheel 3, as indicated at 16. The cone member 7 is also preferably provided with a suitable friction member 17. Surrounding the studs 13 between the bracket 15 to Whlch; the coverplate 14 is secured and the end of the arms l2 of the operating lever 9 are springs 18 which tend to draw or hold cone member 7 away fromthe annular member 5 Within the brake drum.

Securedto the Harige 4 of the Ibrake drum is a flanged member 19, this member serving two purposes, namely, to prevent the entry of dust and the like into the brake drum and also to prevent Athe wheel from becoming disengaged from the driving shaft 2 in case nut 20 which confines the wheel' on the shaft should accidentally come olf.

From 4the above it will be seen that there has been provided a brake of the cone-type which is very simple in construction and which may be readily substituted for the conventfonal expanding brake of the type commonly employed. To install the present type to secure the annular ring 5 within the br e drum as' by means of the screw 6 and to provide the cone member as shown.

What is claimed is:

, In combination with a wheel and axle housing, a brake drum secured to the wheel and an annular friction member secured within the drum and having an inclined surface, a cone-shaped ber shiftably mounted on the housing, a cer-plate for the drum Secured to the housing, a flanged member secured to the drum and overhanging the pe-` ripheral edge @cover-plate, and means. or shifting the cone-member.

In testimony whereof we ax our signatures.

WM. V. JUSTICE. p HUGH ALLON STEWART.
